Specific Precautions and Warnings With AfinitorSome warnings and precautions to be aware of prior to taking this drug include the following:
- Afinitor can cause serious and potentially life-threatening lung problems. Contact your healthcare provider right away if you develop any breathing problems, such as wheezing, shortness of breath, a new or worsening cough, or chest pain. Your healthcare provider may temporarily stop treatment and restart you at a lower dose.
- Because this medicine weakens the immune system, you will be more likely to develop infections during treatment, including pneumonia or other bacterial, viral, or fungal infections. Because these infections may be serious and life-threatening, it is important to contact your healthcare provider right away if you develop signs of infection, such as fever, body aches, or chills.
- If you have had hepatitis B in the past, Afinitor may reactivate your infection. Contact your healthcare if you have signs of hepatitis B, such as:
- Loss of appetite
- Joint pain
- Pale stool
- Dark urine
- Yellowing of the skin or whites of the eyes (jaundice)
- Pain in the upper-right area of the abdomen (stomach).
- Your healthcare provider will perform blood tests before you start this drug, and periodically during treatment, to monitor for potentially serious Afinitor side effects. Blood tests may be used to check your blood cell counts, liver function, kidney function, cholesterol level, and blood sugar level. Your healthcare provider may also want to check your Afinitor blood levels. Make sure to keep all of your medical appointments.
- Afinitor can cause mouth sores and ulcers. Tell your healthcare provider about any pain, sores, or swelling in your mouth. Your healthcare provider can recommend something to help the problem. Do not use any mouthwashes that contain alcohol or peroxide, as they can make your symptoms worse.
